Summary: This study presents a diatomic catalyst with bonded Fe-Ni pairs to improve the efficiency of electrochemical urea synthesis. Compared with isolated diatomic and single-atom catalysts, the bonded Fe-Ni pairs act as efficient sites for coordinated adsorption and activation of multiple reactants, enhancing the thermodynamics and kinetics of the crucial C-N coupling reaction. Additionally, the study achieves high urea yield rate and corresponding Faradaic efficiency.

Summary: We performed Monte Carlo and molecular dynamics simulations on FexNi1-x nanoparticles, investigating their structural features and thermal stability. The simulation results showed that the surface composition of the nanoparticles varied with x, and the arrangement of Fe and Ni atoms was alternate inside the nanoparticles. The melting temperature of the nanoparticles exhibited a non-monotonic dependence on x. Furthermore, we discussed the catalytic performance of the nanoparticles in methane dry reforming, and found that Fe0.375Ni0.625 nanoparticles demonstrated the best catalytic activity, carbon deposition resistance, and sintering resistance.

Summary: The fuel cell is a device that generates electricity from chemical fuels, but its slow reaction rate has been a key challenge. This study demonstrates a novel oxygen-free design of a zinc-nitrate fuel cell that converts nitrate waste into ammonia and generates electricity simultaneously. The cell maintains high chemical conversion efficiency and power density even after long-term testing.

Summary: This study compared the effects of different Fe stress on anammox process, finding that high Fe(II) concentrations may lead to precipitate formation while continuous addition of 30 mg/L-Fe(III) can damage EPS composition. Moreover, addition of Fe(II) could induce nitrate reduction, and OM27_clade and norank_f__Burkholderiaceae may play important roles in this process.

Summary: In this study, CH4-CO2 chemical looping using nanostructured Fe-Ni looping materials for separate H-2 and CO production is proposed. After 25 cycles, 10Fe5Ni@Zr exhibits higher H-2 space-time yield, higher CO yield, and lower deactivation compared to 10Fe0Ni@Zr. The improved performance is attributed to the activation of CH4 over Ni and the deeper FeO reduction caused by product hydrogen.

Summary: The authors reported the structural dynamics of dual-site nickel-iron single-atom oxygen electrocatalysts under reaction conditions, proposing a dual-site pathway for the water oxidation reaction. Single-atom catalysts with maximum metal utilization efficiency show great potential for sustainable catalytic applications and fundamental mechanistic studies. The convenient molecular tailoring strategy based on graphitic carbon nitride as support allows for the rational design of single-site and dual-site single-atom catalysts.

Summary: Fe-Mn-Al-Ni based shape memory alloys are preferred for large scale applications due to their low materials costs and good cold workability. The alloys consist of an A2 structured matrix with B2 precipitates, necessary for thermoelasticity. Thermodynamic considerations show that the undercooling of about 1000 K is caused by the resistance of the B2 precipitates to undergo transformation to the L1(0) structure enforced by the martensitic transformation of the matrix.

Summary: Green rust minerals are considered effective reductants of pollutants, and electron transfer from aqueous Fe(II) to structural Fe(III) in montmorillonite can lead to the formation of green rust at pH around 7.8. This study investigated the pH conditions and the effect of aqueous sulfate concentrations on the formation of sulfate-green rust via this pathway. It was found that the degree of Fe(II) sorption to montmorillonite is critical to green rust formation in the presence of environmentally-relevant sulfate concentrations.

Summary: In this study, a novel sulfidated nZVI core-shell particles (FeS/Fe (0)) were successfully fabricated via a modified post sulfidation approach, showing better performance compared to traditional nano zero-valent iron in removing Cr(VI) from water. The sulfidated iron shell with higher electronegativity can accelerate iron corrosion, facilitate electron transfer, and improve the removal efficiency of Cr(VI).

Summary: The study found that sludge containing added AgNPs can release dissolved silver and colloidal silver. Cl- and Ca2+ in the leaching solution can enhance the release of colloidal silver, which is irregular in shape and ranges in size from 40 nm to 100 nm. This research provides important insights for assessing the fate of AgNPs in wastewater treatment and sludge applications.

Summary: In this study, the reductive dechlorination of trichloroethylene (TCE) by sulfidated microscale zero-valent iron (S-mZVI) was enhanced by promoting the formation of atomic hydrogen (H*) through the introduction of reduced graphene oxide (rGO). The addition of rGO changed the dechlorination pathway and resulted in faster degradation of TCE and a different distribution of degradation products. The electrochemical tests confirmed the occurrence of hydrogen spillover in the S-mZVI/rGO composite, which promoted the reductive dechlorination of TCE by H*.
